Excel caused almost 16,000 Covid-19 test results to be lost

Public Health England (PHE) in the United Kingdom have used an old file format known as XLS for the reporting templates for Covid-19 test results. As a consequence, each template could handle only about 65,000 rows of data rather than the one million-plus rows that Excel is actually capable of.

16,000 positive Covid-19 cases have gone unreported and have only now - days later - been submitted.
